Monday 07/18/2016

Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the El Paso area and the low end of the "Moderate" range in the Dallas-Fort Worth area, with highest concentrations in the afternoon and early evening.

Patchy African dust is lingering this morning in parts of Northeast Texas, raising fine particulate levels in this area. However, dust levels should decrease rapidly today as the dust departs the state. Overall, the daily PM2.5 AQI is expected to net out in the upper end of the "Good" range in this area.

Elsewhere in the state, moderate winds, heavy cloud cover, and/or lower incoming background levels should help to keep air quality in the "Good" range.

Winds may be light enough and incoming background levels high enough for ozone to reach "Moderate" in the Dallas-Fort Worth and El Paso areas, with highest concentrations in the afternoon and early evening.

Increasing background levels associated with building continental haze combined with sufficient local add-on could be enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in the Dallas-Fort Worth area.

Elsewhere in the state, moderate winds and/or lower incoming background levels should help to keep air quality in the "Good" range.

Elevated background levels associated with building continental haze combined with sufficient local add-on could be enough for the daily PM2.5 AQI to reach the lower end of the "Moderate" range in the Dallas-Fort Worth and Houston areas. Another light cloud of patchy African dust may begin to impact parts of South Texas, but at this time the daily PM2.5 AQI is expected to remain in the "Good" range in this area.
